Description

The relay is designed to signal the failure of the brake lights and marker lights that are both on and off in vehicles.

Known interrupter direction indicators and alarm 492.3747. The breaker is produced by JSC "AVAR", Pskov, TU 37.469.002-86. See product catalog of AVAR JSC, Vneshtorgizdat publishing house, 1992.

A reed switch is installed in the breaker, designed to monitor the health of the direction indicator lamps.

The disadvantage of a breaker with a reed switch is a false positive or loss of control functions when exposed to external electromagnetic fields.

Known relay health monitoring lamps 4402.3747. The relay is manufactured by AVAR JSC, Pskov, TU 37.003.1177-83. See the product catalog of AVAR JSC, Pskov, Vneshtorgizdat, 1992

The relay consists of two printed circuit boards connected by jumpers. On the printed circuit boards are five reed switches, radio elements, pins for connecting to the vehicle’s onboard circuit.

The disadvantages of the relay on the reed switches are:

- false positives or loss of monitoring functions when exposed to external electromagnetic fields from closely spaced electromechanical relays or other products with inductive loads;

- a significant number of copper winding wires.

A device for monitoring the integrity of the lamps. See certificate for utility model R.F. No. 6377, application No. 97108148 dated 05/20/97, 6 MKI B 60 S 1/06.

The device consists of two printed circuit boards 1, 2. The boards are interconnected by jumpers 3, on the boards 1, 2 there are elements of the electrical circuit - resistors 4, capacitors 5, current sensors from high-resistance wire 6, microcircuit 7, resistors 8, pins 9 for connect to the vehicle The pins 9 are made with a configuration 10 and are pressed into the boards 1, 2. The device has a housing 11, a cover 12.

This device is taken as the closest analogue (prototype).

Its disadvantages:

- a relatively large amount of fiberglass, because This product contains two printed circuit boards;

- a large number of radio elements (8 resistors, 2 transistors);

- Installing eleven jumpers between the boards is a time-consuming operation;

- The product is not repaired.

The task and the technical result of the utility model associated with the essential features are as follows:

-Multi-channel diagnostics of monitoring the health of lamps and simplifying the design:

- significantly reduced the number of resistors, and also excluded one of the two transistors;

-reduced the amount of fiberglass;

- eleven jumpers between boards are excluded;

- excluded gasket-insulator between the boards;

- Simplified product assembly technology.

This has been achieved by new technical solutions that are in a causal relationship with the technical result.

The essence of the claimed utility model is expressed in the aggregate of the following essential features.

In the already known lamp health monitoring relay, which contains a base with pins installed in it for connecting to the vehicle's wiring network, radio elements, high-resistance wire current sensors and a housing, the following are the distinguishing features:

- based on one printed circuit board;

- one group of pins mounted motionless at the base and connected to the printed circuit board using wires;

- another group of pins installed freely with the possibility of

- movements in the holes of the base, these pins are rigidly connected to the printed circuit board;

- on the printed circuit board there is a microcircuit with the function of multi-channel diagnostics for monitoring the health of the car lamps;

- the wires connecting the group of pins fixedly installed in the base with the printed circuit board are made in length with the possibility of complete removal from the holes of the base of the pins together with the board on which they are fixed.

The above set of essential features in comparison with the prior art allows us to conclude that the proposed technical solution meets the criterion of "novelty."

Figure 1 shows a General view of the relay with a breakout.

Figure 2 is a view along arrow A. The housing and radioelements are conventionally not shown.

Figure 3 is a view along arrow B.

The proposed relay has the following device.

On the circuit board 1 there are elements of the electrical circuit - resistors 2, capacitors 3, transistor 4, current sensors 5 made of high-resistance wire, a microcircuit 6 that performs the electrical functions of multi-channel diagnostics for monitoring the health of the lamps. Each of the wires 7 is connected to the printed circuit board 1 and one of pins 8, 9, 10, 11, 12. These pins are fixedly mounted in the base 13. The pins 14, 15, 16, 17, 18, 19 are rigidly connected to the printed circuit board, installed freely in the holes of the base and can move in these holes.

The relay has a housing 20. The wires 7 have a length that allows, when performing repair operations, to remove the printed circuit board 1 together with the pins 14, 15, 16, 17, 18, 19 from the holes in which these pins are installed.

The proposed relay is installed with pins in the relay and fuse box (not shown). Using a chip 6, the relay evaluates the presence of current flow in the circuit and its magnitude.

For position lamps (not shown in the drawing), the presence of a flowing current is estimated. For stop lamps (not shown in the drawing), not only the presence of a flowing current is estimated, but also its magnitude.

In the event that the lamp is faulty, the microcircuit sends a signal to the control lamp on the dashboard (not shown in the drawing) or the on-board vehicle monitoring system. The relay operates both with the engine turned on and with the car engine turned off, provided the ignition is turned on.

Microcircuit 6 allows the proposed relay to operate either without a transistor or with the use of no more than one transistor.

The proposed relay is technologically simpler, less material-intensive, fiberglass is 50% less, plastics less than 15%, assembly labor is reduced, the total cost of purchased radio elements is reduced.

The use of the claimed solutions allows to increase the reliability, manufacturability of the relay for installation in both manufactured and promising passenger cars VAZ-1118, 2170, 2151 and other modifications of domestic and foreign cars.
